Pentair Impeller 2-1/2 HP for SuperMax / Challenger High Flow Pumps | 355093

The Pentair Impeller 2-1/2 HP (355093) is the OEM replacement impeller for the SuperMax and Challenger High Flow pump lines, rated for 2-1/2 HP service.

The impeller is the rotating component at the heart of your pump's hydraulic assembly. It draws water through the strainer housing and drives it under pressure through the filtration system. A worn or cracked impeller reduces flow rate, strains the motor, and compromises filtration turnover. Replacing it with the correct OEM impeller restores designed hydraulic output and protects the motor from running against restricted flow.

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Pro Tip

Impeller HP ratings must match your pump's nameplate exactly — a 2 HP full-rated and a 2-1/2 HP uprated pump may use the same impeller in some configurations (as with the Challenger High Flow), but the motor's service factor determines which rating applies to your unit. Check the motor nameplate for both HP and service factor before ordering. While the pump is open for impeller replacement, inspect the shaft seal and diffuser O-ring for wear — replacing them at the same service interval avoids a repeat teardown.
